Chronic low back pain and obesity are two common medical conditions. Obesity has been associated with symptoms such as adverse fat distribution and multiple secondary disorders, including low back pain. Obesity is defined as being 30% over ideal weight, which influences normal body mechanics as well as recovery from an injury. ⋯ The results showed that the prevalence rate of facet joint pain in chronic low back pain in Group I or nonobese patients was 36%, in contrast to 40% in Group II, or the obese patient group, with no significant differences among the two groups. The study also showed a false-positive rate of 39% in the total sample, or 44% in Group I nonobese patients and 33% in Group II, or obese patients. It is concluded that the prevalence of lumbar facet joint mediated pain of 40% in obese patients and 36% in patients of normal weight with a false-positive rate of 33% in obese patients and 44% in nonobese patients is similar to the results of multiple previous studies concluding that facet joint mediated pain is a common occurrence in obese patients; however, the incidence of facet joint mediated pain is similar in obese patients and nonobese patients.

Epidural fibrosis with chronic low back pain, nonresponsive to traditional measures of treatment including surgery, is a common entity in modern medicine. Traditionally, epidural steroid injections have been employed to treat chronic low back pain and radiculopathy associated with failed back surgery. Due to the poor effectiveness of epidural steroid injections in post lumbar laminectomy syndrome, epidural adhesiolysis was introduced in the early 1980s. ⋯ Transforaminal ventral epidural adhesiolysis was performed on an outpatient basis in all patients. The results showed 93% improvement initially, which decreased to 71% at 1 month, 57% at 3 months, 43% at 6 months and 21% at 1 year. The results of this case study show that ventral epidural lysis of adhesions with hypertonic saline neurolysis is safe and effective in managing chronic low back and lower extremity pain in patients who failed to respond to other conservative modalities of treatments, including fluoroscopically directed transforaminal epidural steroid injections.

Spinal endoscopy with epidural adhesiolysis is an interventional pain management technique which emerged during the 1990s. It is an invasive but important treatment modality in managing chronic low back pain that is nonresponsive to other modalities of treatment, including percutaneous spring guided adhesiolysis and transforaminal epidural injections. ⋯ Percutaneous endoscopic lysis of epidural scar tissue has been shown to be cost effective and a safe modality. This review discusses various aspects of endoscopic adhesiolysis, including clinical effectiveness, complications, rationale, and indications.

Objective. To evaluate changes in Minnesota Multiphasic Personality Inventory (MMPI) profiles pre- and post-treatment involving intrathecal opioid therapy. Patients and Methods. ⋯ Indeed, patients with the more normal profile pretreatment did not fare as well as those with the more elevated profile. A positive change in MMPI profile from pre- to post-treatment was associated with a higher level of pain reduction. Patient selection therefore should be based not on a single test such as the MMPI, but on consistency across multiple sources of information including physical examination, complaints of pain and disability, behavioral observations, and psychological testing.

This case study describes the therapeutic result of intrathecal administration of ziconotide, a new synthetic neurotoxin derived from the venom of the Philippine marine snail, Conus Magus, to a 48-year-old male with chronic, and previously untreatable, neuropathic pain of an undeterminable etiology. The patient suffered tactile allodynia and reported his baseline pain intensity to be 80 mm on the 100 mm Visual Analog Scale for Pain Intensity. ⋯ Currently, the patient rates his pain at 16 mm and enjoys an improved quality of life. This result suggests that treatment with ziconotide may provide outstanding relief to patients with chronic pain while sparing them the unpleasant side effects associated with other treatments.
